Depends on the crossing. Zebra crossing (the black and white ones with the beacons) they have to stop if you have stepped out and most of the time people will stop if you wait.

Yes, I've always considered this an interesting one - the motorist is only obliged to stop to let you cross if you've already put a foot onto the crossing, by which time you've placed complete trust in the motorist to actually stop! Should they not stop, at least you've got the law on your side and a juicy compensation payout :)

As my memory serves, double cream should whip up nicely. And tell me more of this beef paste. Is this a sandwich filler kind of thing? I'd recommend Shippam's crab paste for sandwiches.
